it is, but whilst I have now got something that works for the mobile number as entered, I am not sure I understand it properly.
whilst I get what certain parts of it are doing I don't fully understand, but having a play and see if I can gain a better understanding later
code extracted from:-
changes in my code:-
added pre setup();
const int EEPROM_MIN_ADDR = 0;
const int EEPROM_MAX_ADDR = 1023;
boolean eeprom_is_addr_ok(int addr) {
return ((addr >= EEPROM_MIN_ADDR) && (addr <= EEPROM_MAX_ADDR));
}
boolean eeprom_write_bytes(int startAddr, const byte* array, int numBytes) {
// counter
int i;
if (!eeprom_is_addr_ok(startAddr) || !eeprom_is_addr_ok(startAddr + numBytes)) {
return false;
}
for (i = 0; i < numBytes; i++) {
EEPROM.update(startAddr + i, array*);*
}
return true;
}
boolean eeprom_write_string(int addr, const char* string) {
int numBytes; // actual number of bytes to be written
//write the string contents plus the string terminator byte (0x00)
numBytes = strlen(string) + 1;
return eeprom_write_bytes(addr, (const byte*)string, numBytes);
}
boolean eeprom_read_string(int addr, char* buffer, int bufSize) {
byte ch; // byte read from eeprom
int bytesRead; // number of bytes read so far
if (!eeprom_is_addr_ok(addr)) { // check start address
return false;
}
if (bufSize == 0) { // how can we store bytes in an empty buffer ?
return false;
}
// is there is room for the string terminator only, no reason to go further
if (bufSize == 1) {
buffer[0] = 0;
return true;
}
bytesRead = 0; // initialize byte counter
ch = EEPROM.read(addr + bytesRead); // read next byte from eeprom
buffer[bytesRead] = ch; // store it into the user buffer
bytesRead++; // increment byte counter
while ( (ch != 0x00) && (bytesRead < bufSize) && ((addr + bytesRead) <= EEPROM_MAX_ADDR) ) {
// if no stop condition is met, read the next byte from eeprom
ch = EEPROM.read(addr + bytesRead);
buffer[bytesRead] = ch; // store it into the user buffer
bytesRead++; // increment byte counter
}
if ((ch != 0x00) && (bytesRead >= 1)) {
buffer[bytesRead - 1] = 0;
}
return true;
}
const int BUFSIZE = 15;
char buf[BUFSIZE];
String myString;
char myStringChar[BUFSIZE];
added in Current();- //so I can read the data without having to input again
eeprom_read_string(0, buf, BUFSIZE);
Serial.println(buf);
added in Number():-
Serial.println("Saving variable string to address 0");
myString=no1; //changed this line to use the string as inputed in the serial monitor, rather than the pre formatted number.
myString.toCharArray(myStringChar, BUFSIZE); //convert string to char array
strcpy(buf, myStringChar);
eeprom_write_string(0, buf);
Serial.print("Reading string from address 0: ");
eeprom_read_string(0, buf, BUFSIZE);
Serial.println(buf);
